that was definitely news of the month!!

thank you guys.

I knew you will come out with solution. I gave you time until end of April :-)

This is half month before

why all this talking from dev-team that its impossible to downgrade? I just didnt buy that.

While this is great news, it’s only for those on 5.08 which will be the minority of 3G iPhone owners. When 5.09 and 6.02 can be unlocked, that will be a great day.

yeh mark is rite, as for me i have got 5.9!! so i can’t downgrade!!!

problems…

to me it says No such file or directory.

In which folder Im putting this? I tried in:
root/Applications
and
root/private/var/mobile/Applications

none of them worked

any chance for some detailed instructions

thx

hi, i tried using phasebandowngrader, but the problem is my iphone suddenly turn off when im trying to check the bootloader to terminal, then when it turns on theres no sounds and it doesnt display the FW…and also it keeps on searching for network… when i try to do recovery mode it display’s ” your iphone is in recovery mode, and i you have to restore it before it can use itunes” here’s another problem, the itunes doesnt want to launch…
is there anything i can do to fix this? any help will be highly appreciated.

I checked on several places and it seems that nobody manage to do it.

bit more instructions would be fantastic

thx

Permission denied!!

What I mean is the 3G iPhone has multiple versions of bootloaders that can be on the phone, depending on when you bought it. 5.08 was the first bootloader. Apparently you needed to buy the iPhone on launch day to get this version, I don’t know.

This downgrade doesn’t work for everyone with a 3G iPhone. People are getting all crazy and they think it does work for every iPhone. Maybe in time it can be updated, or a new exploit found to work on the 5.09 and 6.02 bootloaders so that everyone, and not just a very small percentage of 3G iPhone owners can use it to downgrade.

And what’s up with everyone dropping the 0 from the version number? My bootloader is 5.09 not 5.9. I’m sure this holds true for 5.08 and 6.02.
All this does is cause even more noob confusion.

And you are 100% certain that you have the 5.08 bootloader? If you don’t this won’t work.

plEASE help me to, same problem

kevinelfring@gmail.com

Im a noob at this, been waiting for the downgrade to be available for ages!
Can you please help me check my baseband, maybe write more understandable steps than the ones on the link supplied (using minicom)

Thanks Very much

From Malta :)

Hi, My I found out that my bootloader is 5.9 but i had already run the ./phasebandowngrader. Please tell me some of the problems i may have in the future if crack is made for the 5.9 bootloader.

Please help

KCingx

I have the same problem :)

BootLoader: ICE_BOOT_05.08_G2M3S2
ModemFirmware: 2.30.03
__________________________________

The instalation worked ok I fallowed the steps … everything’s ok … the phone restart’s after 3-4 minutes after the instalation … when it’s done i check for my modem firmware and it’s 2.30.03 instead of 2.82

Should i try at the restart to enter recovery mode and put the 2.2 firmware ?

I hope u guys will find a solution for 5.09 …. great job though

sorry I am retarded, and just thoroughly read attnck’s post!

thanks attnck

I finished the entire process, and everything went smoothly. Restarted, still 2.30…

Hi,

I have root access to the Iphone and can access all directories with the exception of /Applications… I can therefore copy the phasebandowngrader file to this directory. How can I change the permissions?

same here, plz help

can u make a video to show how it works

did as in description and still 02.30.03 and bootloader is 5.8

Succesfully completed all steps.
Bootloader definitely 5.08
PhaseBandowngrader said it was successful.
Restarted – but still 2.30 as appears in settings.

Is it possible the downgrade was successful but the display in the settings menu doesn’t change? Is there another way to check the firmware version..?

Has anyone successfully downgraded?

Again… Has ANYONE on this site successfully downgraded using this software??

Doesn’t look like it working. Did see anyone post with succeed.

And one other thing… If you get a error saying Permission Denied

Before the last entry

when you see
|—————————————————–|
| localhost:/Applications/phasebandowngrader root# |
|—————————————————-|

on your iPhone`s screen

type
|—————————-|
|chmod 755 phasebandowngrader|
|—————————-|

or try 777 if 775 doesn`t work. Hope this helped.

Regards
Epic

i did all the steps, restarted and it still says i have 2.30 baseband. Any thoughts ?

@will what do u mean by u patched the .fls

Yes, Will is right, the .fls file included is not patched. You can either patch it yourself with the downgrade.patch that geohot posted or you can grab the patched .fls here:

http://rapidshare.de/files/46771253/ICE2_02.28.002.fls.html

Can you please give a more detailed description? You lost me at you “patched the file”, I’m not sure how to do this with out directions and I don’t think I’m the only one not familiar with how to patch the file.

6.02 :( – if it’s any consolation :(

By the way JackB, your attacked file has a extra number: isnt it should be ICE2_02_28_00.fls?

same as by me,
it will not work by my iphone,
it said it’s downgraded but it doesn’t downgrade

Confirmed work on 3G 5.08BL
http://www.iclarified.com/entry/index.php?enid=3583

You’re right, I’ve uploaded my backup copy of unpatched .fls.
Here is the right version:
http://rapidshare.de/files/46778945/ICE2_02.28.00.fls.html

Hi,

Those who have had ‘permission denied’ error is possible you did not login as ‘root’. If you are using Mobile Terminal, please type ‘su’, and get password prompt, type in root password ‘alpine’.

Regards

i get the message:

Press any key to continue….

i pressed any key, and nothing happend!

any ideas?

Surely this exploit will work on any phone with 5.8 (like mine) and if so is there a patched version to downgrade from 4.xxx to 2.28.00 for those who upgraded to 3.0 beta and then decided it was too buggy??

I tried everything that was discussed here. I tried it with both .fls files and it always showed that it was successful but when I checked it still showed that the baseband was 02.30 . I even ran it through manually. Still with no luck. I then saw that someone had posted the iclarified link for DownBB. I tried and it worked like a charm. The tutorial was easy. I have spent a couple of days with this and am very happy that I can finally use my 3G phone. Thanks guys for your help!!!

nothing will work, it is wasted time, trust me

Is there a way to SSH to a command shell if your phone is not jailbroken? I cant install Cydia because my phone is on the most current versions of baseband and OS.

i looked in youtube and there is a video showing you a better method to do the baseband downgrader, i looked it and did what they said and i am a happy user of my 3G with yellowsn0w after i did the downgrade.

Thanks, going to try this later today.

jose, link would be nice….

hi guys i just bought my iphone yesterday from i shipper that shipped him from amerika to europe
so i dont know when it whas pruschased.
wil this downgrade hurt your iphone is your on 5.9?

Hello!
Congratulations, but could you tell us your bootloader version? My BB ver. is 6.02.

Hey guys! I heard that if someone is trying to downgrade the BB version to 2.28 and he hasn’t got bootloader version 5.8 then this procedure can damage the phone.. Is it true? I tried to downgrade, the programming was success, but nothing happened, my BB is still 2.30.03.
The is stable I have no problem yet.
I bought a Q-SIM (turbosim) and it’s working now, i can use my phone with it…

pls some one help i upgrade my iphone 3g to fucn 3.0 beta 3. than downgrade back to 2.2.1 and steel doesnt work and stuck on 04.24.02 bb .my phone is wired no signal. how can i downgrade baseband from 04.24.02 to down guys:(( ! thanx

I get “DownBB: command not found”

But I already installed iclarified source.

Please advise

Successfully downgraded to 2.28 from 2.30.03
Yellowsn0w works again!!!!!!!

simply download DownBB in Cydia.

Go to mobile terminal type in
1. login
2. root
3. Password:alpine
4. Enter DownBB
6.Wait and confirm “yes”
After is down your iPhone will restart.

[Reply]

I don’t think you can… there have been numerous warnings all over the web that upgrading to 3.0b OS will kill your ability to use other operators as yellowsn0w will not work on the new baseband and there is no downgrade hack for 3.0 OS as yet. Hopefully you’ll find a solution in a few months when the 3.0 OS is officially released.

Hi!

If I have been upgrading my Iphone 3G wth OS 3.0 Beta 2, and I cant use it anymore(until late summer or so, when a fix ha been made)

Could this be a solution:

http://www.mooglex.com/mog/node/4

Or is it jut fake? Anyone tried that?

Thanks in advance.

Hey,

I did the downgrade on my Phone, everything went through but now my phone doesn’t have any signal at all! It keep saying no service or no sim. or it have a bar with one dot

Can anyone explain? or help me on this? Please??

Thank you so much

It seems that 3.0 beta 3 updates the baseband once again and kills the ability for turbosim: i-smartphone for 3G to work. Only AT&T sim connects now. Has anyone been able to downgrade from latest baseband to previous baseband in 3.0 beta 2?

Thanks

Is there any update on downgrading 5.09 bootloader. Is there any hope in the near future to be able to do that?

what about downgrading 5.09 bootloader. Is there any hope in the near future to be able to do that??????????

So in order to try any of this, you must first jailbreak the phone, which you cannot unlock because its baseband 2.30, so how are you suppose to run DownBB or anything in relation with any installation if the phone is locked? As far as the downgrade goes, has anyone had any success with the downgrade, and how are you suppose to check when your phone was made, it took me to wiki and didnt show me jack. Thanks for the effort guys, doing an awesome job but i just had some questions before i messed with the iphone and couldnt be able to use it anymore.

Turn off 3g

my bootloader 5.08 i try to downgrade 5 times but still get erro when i enter SU pass alpine enter downbb still not found :-(
